12description: |
13  This LEDs controller was first used on BCM63138 and later reused on BCM4908,
14  BCM6848, BCM6858, BCM63138, BCM63148, BCM63381 and BCM68360 SoCs.
15
16  It supports up to 32 LEDs that can be connected parallelly or serially. It
17  also includes limited support for hardware blinking.
